The Apex Polymer Action Enhancement Trigger Kit directly replaces the factory hinged trigger with a solid body polymer trigger with a center mounted pivoting safety. The rounded face of the trigger provides a smooth comfortable surface for the shooters finger while firing. The trigger also reduces pre-travel by approximately 20% and over travel by 10% when compared to the factory trigger and is perfect for use in SD and Sigma pistols already equipped with an Apex SD or Sigma Spring Kits, but works as a standalone component as well.
